The main rotor of the doomed helicopter that crashed into the Hudson River was finally recovered Monday — as investigators continue to probe what caused the deadly tragedy. Divers were spotted pulling the rotor from the murky river Monday afternoon — days after the chopper went down off Manhattan, killing a Spanish family of five and their pilot. The rotor will likely offer up clues as to how the sightseeing helicopter managed to break apart in midair and plunge into the water last Thursday. Footage captured by horrified witnesses showed parts of the aircraft tumbling through the air after it broke apart some 18 minutes into the flight. One clip showed the rotor still spinning without the helicopter as it plummeted. Large chunks of the mangled wreck — which was owned and operated by New York Helicopter — were quickly pulled from the river in the immediate aftermath. The bodies of the six victims — including pilot Seankese Johnson, Siemens executive Agustin Escobar, 49, his wife, Mercè Camprubí Montal, 39, their three children, Victor, 4, Mercedes, 8, and Agustin, 10, were also retrieved from the water. The retrieval of the debris came soon after the Federal Aviation Administration revealed the tour company would be shutting down operations immediately.
